Can You Bring Your Phone in a Sauna? (iPhone & Cell Phones?)

Some sauna users may be tempted to keep their phones with them for entertainment or communication purposes, it’s important to understand the potential risks and implications of doing so.

Bringing your phone into a sauna is not recommended due to the extreme heat and humidity inside the sauna. Saunas typically exceed the maximum operating temperature of a phone, which can permanently damage the device. Moreover, saunas are meant to be places of relaxation, meditation, and mindfulness, and having a phone can be a distracting element in this serene environment.

Both iPhones and Android phones, despite having waterproof or water-resistant ratings, are not designed to withstand the high temperatures and steam found in saunas. Even if your phone survives the heat, the steam can seep into the device and cause internal damage over time.

In this article, we’ll explore the reasons why taking your phone into a sauna is not advisable and why saunas can be detrimental to the longevity and performance of your phone. Additionally, we’ll address some common FAQs and shed light on the potential risks associated with bringing electronic devices into saunas. So, before you consider keeping your phone with you during your sauna session, it’s essential to understand why saunas are not a suitable environment for your beloved device.

Can You Bring Your Phone to the Sauna?

You should not take your phone in a sauna because a sauna exceeds the recommended maximum operating temperature of a phone which is 113°F (45°C). The heat and humidity can permanently damage your phone. Moreover, people might object to bringing a device with a camera into a place where everyone is semi-nude. And lastly, a sauna is a place to rest, meditate and practice being mindful. A phone is a distracting element in the environment and most people won’t appreciate you bringing a phone in a sauna. 

Some saunas even have clear rules against bringing a smartphone inside a sauna. For instance, King’s Spa allows phones inside the sauna only during emergencies. Here’s what they said about the usage of phones: “Except in the event of an emergency, members/guests may only use their mobile/smartphones outside of the wet spa/locker rooms and dry sauna rooms.”

Can You Take an iPhone in Sauna?

It’s best not to take an iPhone into the sauna. Apple’s latest iPhones (iPhone 11, iPhone 12, and iPhone 13) have an IP68 rating. In other words, the phones can survive underwater for hours. One can say that iPhones would do just fine in humid places like the sauna or steam room but consider the heat and the hot steam. Hot steam affects your phone differently than liquid water.

If you take an iPhone into a sauna, the system will start heating and it will set off the iOS’ temperature warning system. The phone will then switch off temporarily to avoid damage. So you can’t use the phone inside the sauna. 

Apple has officially declared that customers should not use iOS devices in baking hot environments. They said: “Using an iOS device in very hot conditions can permanently shorten battery life. Store the device where the temperature is between -4º to 113º F (-20º and 45º C). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.”

Taking iPhone 7 in Sauna?

What About Android Cell Phone in Sauna?

You can’t use an Android cell phone in the sauna. Sure, many Android phones have a good IP rating meaning you could leave your cell phone in the bath or underwater for a long time and it would still work just fine. But if you expose an Android phone to high temperature, it will shut down and try to cool itself down.
